nokia BT car kit and T610 feedback

I just started using the great T610 in my car on my Nokia BT car kit, and
the caller gets loads of feedback, this never happened on my nokia 6310i .
Someone mentioned duplexing ???? any ideas how I can sort this...

I'm using the T610 with the Nokia CARK112 BT kit with no problems with
feedback. Haven't done anything special so can't give any advice but at
least it shows the combination can work
